The benefits of guided wave radar level gauges

A guided wave radar level gauge (Guided Wave Radar, GWR) is a type of level measurement instrument based on microwave technology that measures the level, interface, or solid material level by propagating electromagnetic waves along a guide rod or cable. Its core advantages lie in high precision, strong interference resistance, and wide applicability. Here are the specific benefits:

High precision and reliability ? Millimeter-level accuracy: Utilizing Time Domain Reflectometry (TDR) principle, measurements are unaffected by changes in medium density, temperature, or pressure, achieving accuracy of ±1mm.

? Stable signal transmission: The guided wave structure (rod/cable) confines radar wave propagation, preventing diffusion loss, especially suitable for small containers or complex operating conditions. Strong interference resistance capability

? Overcoming steam and foam effects: Compared to ordinary radars, the guided wave structure can penetrate condensation mist or foam, reducing false echo interference.

? Dust and turbulence resistance: Suitable for environments with intense stirring or high dust levels (such as cement silos, reactors). Multi-functional applicability

? Dual measurement of level and

5. Economic Advantages

No need for tracing or purging: saves on auxiliary equipment costs compared to float and differential pressure meters.

Long-term stability: no drift problems, long life of more than 10 years.

Typical application scenarios

Complex working conditions: high temperature oil tanks in refineries, chemical reactors (strong corrosion), LNG low-temperature storage tanks.

Highly demanding measurement: clean container in pharmaceutical industry, sanitary storage tank in food industry.

Interface monitoring: crude oil dewatering tanks, sewage treatment layered detection.
